What coins in your portfolio do you have doubts about?

It's not easy deciding how to diversify your portfolio and especially so with just how many coins there are out there. There are of course Bitcoin and Ethereum which are very safe in my opinion and will break their ATHs again, but that's not the case with a lot of the coins that people decide to add to their portfolios.

It could be alts, it could be coins that are new, low cap, or you just got it shilled to in the reddit comments. But you do have to ask yourself the question that if we enter a Crypto winter, will your coin be able to make it through? Will it survive?

So what coins do you have in your portfolio that you have doubts about, about which you're uncertain if you should sell or not?
